* 6182 - start of support for safe handlesKartik Agaram2020-04-031-3/+3
| | | | | | | | | | | | | | So far it's unclear how to do this in a series of small commits. Still nibbling around the edges. In this commit we standardize some terminology: The length of an array or stream is denominated in the high-level elements. The _size_ is denominated in bytes. The thing we encode into the type is always the size, not the length. There's still an open question of what to do about the Mu `length` operator. I'd like to modify it to provide the length. Currently it provides the size. If I can't fix that I'll rename it.

* 5897 - rename comparison instructionsKartik Agaram2020-01-161-21/+21
| | | | | | | Signed and unsigned don't quite capture the essence of what the different combinations of x86 flags are doing for SubX. The crucial distinction is that one set of comparison operators is for integers and the second is for addresses.
* 5883 - drop the `ref` keywordKartik Agaram2020-01-121-14/+14
| | | | | | | | | | When I created it I was conflating two things: a) needing to refer to just the start, rather than the whole, and b) counting indirections. Both are kinda ill-posed. Now Mu will have just `addr` and `handle` types. Normal types will translate implicitly to `addr` types, while `handle` will always require explicit handling.

* 5804Kartik Agaram2019-12-081-25/+27
| | | | | Try to make the comments consistent with the type system we'll eventually have.
* 5790Kartik Agaram2019-12-051-2/+2
| | | | | | Standardize conventions for labels within objects in the data segment. We're going to use this in a new tool.

| | | | Thanks Andrew Owen for reporting this typo.
* 5668 - start reorg to permit syntax sugar in layersKartik Agaram2019-09-191-1/+1
| | | | | | | | | | | | | | | | | | | Right now we always build the library before any apps. Apps are where our syntax sugar translators (sigils, calls, braces) live. So we can't use sugar in the standard library. New idea: move all code for SubX phases into the top-level. Perhaps we should also just build a single file rather than pipeline stages. But for now we'll build each phase by building up to some specific layer. This will simplify test_apps and move lots of one-off logic to a more standard form in test_layers. I'm also going to reorg existing layers so that we introduce each phase at a point where it mostly only gets the helpers it needs. This commit itself is just cleaning up some common strings. Using explicit names for them streamlines binaries a bit.
